Description

Technical Field

[0001] This invention relates to the field of spinneret technology, and more particularly to an elastic fiber profiled spinneret and spinning assembly. Background Technology

[0002] The spinneret is a crucial component of spinning machinery and one of the most critical parts of the spinning process. Typically made of metal, it contains numerous tiny holes or spinnerets. The spinneret's main function is to transform fiber raw materials into filaments, extruding the fiber raw materials through the spinnerets to form filament bundles. Each spinneret corresponds to a filament, and the number of spinnerets on the spinneret can vary from tens to thousands depending on the needs. The design and manufacturing of the spinneret are extremely important because they directly affect the quality and performance of the filaments during the spinning process. The spinneret holes on the spinneret usually have very small diameters, typically on the micrometer scale; the size of the hole diameter directly affects the diameter and performance of the filaments, with smaller hole diameters producing finer filaments.

[0003] Currently available spinnerets have very small orifices, and due to the stickiness and impurities of the fiber raw materials, some of the spinning material adheres to the surface of the spinneret during spinning. If the spinneret orifices become clogged, it will cause the filament diameter to become thicker, the fiber bundle flow to be uneven, and may affect the normal operation of subsequent spinning processes. At the same time, the spinning assembly cannot self-clean in time, and after clogging, the spinneret needs to be disassembled and cleaned, which is time-consuming and labor-intensive. Therefore, we need an elastic fiber profiled spinneret and spinning assembly. Summary of the Invention

[0004] Based on the technical problem that traditional irregularly shaped spinnerets and spinning components are prone to clogging of the spinneret orifices and cannot be automatically cleaned, this invention proposes an elastic fiber irregularly shaped spinneret and spinning component.

[0005] The present invention proposes an elastic fiber shaped spinneret, which includes a fixed base plate, and a fan-shaped hole is opened in the middle of the top of the fixed base plate. The fan-shaped spinneret is detachably installed on the inner wall of the fan-shaped hole at the top of the fixed base plate by screws.

[0006] A spinning assembly includes a spinning device fixedly mounted on the center of the bottom of a fixed substrate by screws, the spinning device being connected to the bottom of a fan-shaped spinneret. A rectangular vertical plate is welded and fixed to the rear end of the top of the fixed substrate, and a cleaning mechanism is fixedly mounted on one side of the top of the rectangular vertical plate by screws. A slide rail is fixedly mounted on the bottom of the front end of the rectangular vertical plate by screws, and a rotating mechanism is slidably mounted on the front end of the slide rail. A sliding track groove is fixedly mounted on the top of the center of the front end of the rectangular vertical plate by screws, and a transmission mechanism is slidably mounted on the front end of the sliding track groove. A power mechanism is fixedly mounted on the rear end of the rectangular vertical plate away from the cleaning mechanism by bolts. A spring mechanism is fixedly mounted on the rear end of the center of the bottom of the fixed substrate by screws.

[0007] A further feature of this invention is that the power mechanism includes a fixed plate, which is fixedly mounted to the rear end of a rectangular upright plate by bolts. Both ends of the top of the fixed plate are fixedly mounted with bases by bolts, and the tops of the two bases are fixedly mounted with the same servo motor by bolts. A semi-circular groove is formed on the top of the rectangular upright plate near the servo motor, and a bearing ring is welded to the inner wall of the semi-circular groove. The outer circumferential wall of the servo motor output shaft is fixed to the inner wall of the bearing ring, and a gear plate is welded to the front end of the outer circumferential wall of the servo motor output shaft.

[0008] A further feature of this invention is that the rotating mechanism includes a rectangular plate, the rear end of which is slidably mounted on the front end of a slide rail. A toothed rod is welded and fixed to the center of the top of the rectangular plate, and the protruding teeth at the top of the toothed rod mesh with the bottom of a gear plate. A bearing sleeve is provided at the center of the front end of the rectangular plate. A rotating rod is welded and fixed to the inner wall of the inner ring of the bearing sleeve, and a turntable is welded and fixed to the front end of the outer wall of the rotating rod. A rubber ring is provided on the outer circumference of the turntable. A rotating shaft is welded and fixed to the front end of the rotating rod, and multiple sets of cleaning brushes are provided at equal intervals on the outer circumference of the rotating shaft by screws.

[0009] A further feature of the present invention is that a base rod is fixedly mounted on the top of the fixed base plate near the servo motor by screws, and a rubber strip is provided on the top of the base rod.

[0010] A further feature of the present invention is that the transmission mechanism includes a sliding rod, which is slidably mounted on the front end of the sliding track groove. A sleeve rod is welded and fixed to the middle of the front end of the sliding rod, and a folding rod is welded and fixed to the middle of the top of the sliding rod. A connecting rod is welded and fixed to the front end of the servo motor output shaft, and an elliptical plate is welded and fixed to the front end of the connecting rod. A sleeve block is welded and fixed to the front end of the elliptical plate at a position off-center. A transmission rod is sleeved on the outer circumference of the sleeve block, and the other end of the transmission rod is rotatably sleeved on the outer circumference of the sleeve rod.

[0011] A further feature of the present invention is that the impurity removal mechanism includes an air suction pipe, which is fixed to one side of the top of the rectangular upright plate by screws, and a piston block is embedded in the inner wall of the air suction pipe, and the other end of the folding rod is fixed to the center of the piston block.

[0012] A further feature of the present invention is that a connecting pipe with an internal one-way valve is connected through the center of the side of the air extraction and blowing pipe away from the servo motor, and the connecting pipe passes through the rectangular upright plate and the fixed base plate.

[0013] A further feature of the present invention is that the elastic mechanism includes an elastic airbag, which is fixed to the bottom of the fixed base plate by screws, and the other end of the connecting tube is connected through the rear end of the elastic airbag. The front end of the elastic airbag is connected through an air-jet block, which is fixed to the middle rear end of the top of the fixed base plate by screws.

[0014] A further feature of the present invention is that a fixing frame is welded and fixed to the bottom of the fixing base plate, and the elastic airbag is located inside the fixing frame. Circular holes are opened on both sides of the bottom of the fixing frame, and the same U-shaped plug rod is inserted into the inner wall of each circular hole. The two top ends of the plug rod are fixed with the same extrusion plate by screws, and springs are fitted on the top of the outer circumference of the plug rod.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention utilizes a servo motor, gear plate, rack, rubber strip, rubber ring, and cleaning brush. When the servo motor drives the gear plate to rotate, it moves along the slide rail via the meshing rack. During this movement, the rubber ring contacts the rubber strip. When rotating in the opposite direction, the rubber ring rolls on the rubber strip, causing the rotating rod and rotating shaft to rotate. After rapid movement, the rotating rod and rotating shaft continue to rotate due to inertia, stopping above the fan-shaped spinneret and rotating rapidly to clean the spinnerets on the fan-shaped spinneret, achieving an automatic cleaning effect.

[0017] 2. This invention is equipped with a suction blowing pipe, a transmission rod, an elliptical plate, and other devices. During use, the elliptical plate and the transmission rod drive the sliding rod to move back and forth in the sliding track groove, thereby creating a suction and extrusion effect. The suction blowing pipe draws in gas, which blows onto the surface of the spinneret during extrusion, removing the impurities cleaned by the rotating cleaning brush, thus achieving a thorough cleaning effect.

[0018] 3. The device of the present invention is equipped with elastic airbags, springs, and extrusion plates. When the servo motor runs at high speed, the piston block will quickly squeeze the gas out and inject it into the elastic airbag. The elastic airbag itself contracts and the spring pushes the gas inside slowly out. The gas inside does not flow in reverse under the action of the one-way valve. It is blown onto the surface of the fan-shaped spinneret by the jet block to achieve a continuous blowing effect. Attached Figure Description
